MECHANICAL-PROPERTIES AND BONE DENSITIES OF CANINE TRABECULAR BONE

The purposes of this study were (1) to evaluate the mechanical propert ies of canine epiphyseal cancellous bones from adult canine femoral he ads, femoral condyles, tibial plateau, and humeral heads, using indent ation and compression tests, and (2) to measure bone densities (appare nt density and ash density) of these cancellous bones so as to develop a normal data base of mechanical strength and bone density. The corre lations between the two mechanical tests and between these tests and b one densities were also considered. The results showed all of the thre e mechanical parameters, ultimate load, stiffness, and ultimate streng th, measured by the indentation test were higher than those measured b y the compression test. Correlation analysis showed that the two sets of mechanical values correlated well (r = 0.823-0.952, p < 0.01). The apparent density and ash density correlated well with the mechanical p arameters determined by the two types of mechanical tests (r = 0.737-0 .966, p < 0.05). (C) 1998 Chapman & Hall.
